18. Kxb2

Now here a move like 18.fxg6 must never be forgotten. After 18...Nxd1 white can deliver check with pawn or bishop, but after 19.fxf7 Kh8 or 19. Bxf7 Rxf7 20.gxf7 Kf8 There are several hanging white pieces and black gains free hand to operate at the queenside. Black king looks airy but there are no quick ways to kill. I don't remember what I had prepared to it at the time of this game.... Maybe I should Fritz the position. |

18... Rxc3 19. fxg6 Rxb3+
|
And so black finally gets rid of the white LSB, at the cost of an exchange. Not many other possibilities here, though. The white king gets a bit airy and now Black is constantly looking ways to exploit it. |

20. cxb3

There is something to be said about axb3 as White does not seem to be interested in challencing the c-file... |

Now black has, somewhat superficially, actived his other rook. However, the f-file turns out to be a good highway to action and the rook now has an ideal square on his mind - f2. |

This might be a minor mistake. I think 21.Rc1 would've been more awkward move to meet. |

Interesting possibilities here; 21...Nxe4 is worth analysing. If white captures, then after ...Rf2 blacks attack would most probably crash trough. But I couldn't see anything acceptable after the simple 22.Rc1, so I decided to renew the threat while activating the queen. Now White takes blacks word and makes a preventive move. |

One gets a feeling that there should be something better here... |

Once again renewing the threat; now it is 23...Nxe4 24.Qxe4 Bf5 when the queen is a goner since the d4-knight is pinned against checkmate on b2. |

23. Bh6

Now white decides to act on the kingside deciding to answer ...Nxe4 with Bxg7 with complications that are far too hard to analyze for me. |

|
|
|
23... Nxe4
|
Black steps bravely into the action. With this move black is willing to sacrifice at least a piece, in some lines even more. |

|

|
24. Bxg7
|
It is not the calculating task that is hard but some positions just are not easy to asses. This is clearly the best move in this situation, removing the "checkmate-pin" of the knight. |

|
|
|
24... Rf2 25. Nc2
|
Now it looks like black runs out of steam, he is down on material and the queen is threatened. |

25... Bf5

Jacob Aagaard, one of my favourite chess authors once established a "90% rule" - 9 times out of ten the move you want to make for positional reasons works out tactically, too. So, black wants his whole army to work together and this is clearly the best square for this bishop. So we can forget such minor tactical problems as a hanging queen. It is still not sure if blacks gamble work out - he is down a rook for three pawns. However, the activity of black forces and the incoming pin of the knight will give him such a pressure on whites position that (or that is what he trusts) black will win atleast an exchange back and then have three pawns for the exchange - two of them doubled and isolated, though.
I would like to add that this sort of move is very, very hard to resist. It is so aesthetically pleasing that black felt that he must try it. That is probably why he played 23...Nxe4 in the first place. |

Clearly the best. 26.Nxa3 Nc3 27.Kc1 Nxa2# or 27.Ka1 Rxa2# |

26... Qc5

Queen exchange is no problem for black, there is other goals for an attack than a checkmate. All his pieces are better than their white counterparts and he has a nice bind on white, not to mention the two central pawns that may turn into a great force in a endgame. One gets the feeling that white's extra rook is not doing everything it can... |

|
|
|
27. Qxc5 Nxc5
|
Now it becomes clear that white cannot mantain all of his material lead. He must now decide the best way to give up the exchange back.
It is suprising how active all black pieces became. Not the same can be said about white pieces, the b2-bishop looks nice, but without other pieces it does nothing. The knight is doomed to a poor square and the rooks can't do much right now. Lead in developement is not, however, a permanent advantage, so black must do something with it. |

28. Rdc1

Of course it's not necessary to lose a whole piece. |

|
|
|
28... Nd3 29. Rcf1 Re2
|
White knight cannot move and black threatens ...Nxb2. White decides to get rid of the suprisingly active black bishop. |

|
|
|
30. Rxf5 gxf5
|
So black has three pawns for a bishop. White has a passer and now his rook is in a good position, but black has four (!) connected passed pawns. The game is not over yet, but now it sure looks like black has the advantage - his rook and knight are better than white's so the question is: can the pawns overcome the bishop? |

If the bishop goes, then it's all over for black. Knights are not as good against pawns as bishops. |
